4 OPERATIONAL & MAINTENANCE ACTIVITIES - 2005

4.1 Risk Management Review No formal AS2885 risk assessments were carried out on the South East Pipeline system during 2005 no new risks were identified. A further risk assessment will be carried out in 2007. 4.2 Training The Epic Energy management team is committed to developing the skills of their employees to meet the operational needs of its business. During 2005 staff training was conducted both in-house and externally and covered a range of items including: • “POMS” awareness training • Ongoing “On the Job” training of permanent contractors in the South East Region • CP monitoring training and advanced courses completed. (conducted by the Australian

Corrosion Association) • Senior First Aid training (conducted by St John Ambulance Australia) • Defensive driving (Collision avoidance and 4WD training) • Pipeline excavation training • Permit to Work training • Emergency Response Site controller training • AS2885 Awareness training • CP monitoring training (conducted by the Australian Corrosion Association) • CP advanced training (conducted by the Australian Corrosion Association) • Manual Handling training • Atmospheric Testing training • Confined Space entry • Work Zone traffic management • First Five minutes Fire training • Pipeline locator use • Pipeline Surveillance and easement activities training • Introduction to Pigging training • Security Awareness training • Heat stress training • Hazardous Electrical equipment selection and maintenance training 4.3 Operations & Maintenance Activities Operations and maintenance activities have been conducted at programmed frequencies throughout the year;. During the course of 2005, the following activities were conducted: • Road Patrols have been conducted on a monthly basis; all action items identified during the

patrols were rectified immediately by the patrolling officer or completed during regular maintenance visits by Epic Energy personnel.

• Monthly Meter, Off-take & Scraper site inspections were carried out by Epic Energy authorized contractors with no major issues identified.

• Inspection and servicing of all fire extinguishers took place with no major issues identified. • Six monthly maintenance was carried out on all MLV’s and Pig Vessels during the year.


Page 7 of 19

• An external contractor conducted pressure vessel inspections on all vessels on the SEP system.

• A pipeline system “Inline Inspection” pigging program was conducted and details are provided further in this report.

• Six monthly maintenance was carried out on all meter stations and associated equipment. • Three monthly Accuracy Verification Testing was conducted at all meter stations. • Administration of the Freecall 1100 “Dial Before You Dig” system was undertaken during the

year with 20 of calls received relating directly to the SEP system. 4.3.1 Patrol Activities Scheduled ground patrols of the pipeline easement and above ground facilities were conducted by Epic Energy authorized contractors throughout the year. The ground patrols ensure that the following pipeline activities are addressed:

• signage is in suitable condition and if not, repairs are affected as soon as is practically possible. Any issues not addressed during the patrol are fed back into the CMMS.

• there are no unauthorized activities occurring along the pipeline route or at any of the facilities

• restoration of any soil erosion due to wind and water is addressed

• there are no leaks occurring at any of the pipeline facilities or along the pipeline route

• all sites are secure, kept clean, neat and tidy

• Items including above ground pipe coating condition, fences, gates, padlocks, signage, fire extinguishers, weeding and other housekeeping activities are addressed at all of the facilities associated with the pipeline system.

During 2005 a report was given by PIRSA that a gas test near the pipeline had revealed a small amount of gas present above the ground. The area in question was patrolled both by road and on foot and constant gas monitoring by Epic Energy personnel could not find any evidence of a gas leak. GIS data from PIRSA showed that the 2 locations where the gas tests were conducted were some distance from the pipeline. In 2005 no significant issues were identified during any of the patrol or other routine maintenance activities. 4.3.2 Cathodic Protection During March and September 2005 full line CP surveys were undertaken on the SEP system.

The Glenco to Mt Gambier pipeline is protected by six sacrificial magnesium anodes. The ”On” potential readings and current density measured during this survey are consistent with a well coated and protected pipeline with few coating defects. The survey results show that there are no sections of the pipeline which are under protected.

The Katnook to Apcel pipeline is protected by ten sacrificial magnesium anodes. The ”On” potential readings and current density measured during this survey are consistent with a well coated and protected pipeline. The survey results indicate that there are no sections of the pipeline which are under protected.

The Nangwarry pipeline is protected by 4 Zinc anodes. The ”On” potential readings and current


Page 8 of 19

density measured during this survey are consistent with a well coated and protected pipeline. The survey results indicate that there are no sections of the pipeline which are under protected.

The Safries Lateral pipeline is protected by five sacrificial magnesium anodes. The ”On” potential survey results indicate that there are no sections of the pipeline which are under protected.

A number of minor action items arose from these surveys and are being completed as part of the routine maintenance program. The “On” potentials from the surveys conducted indicated that the pipeline system is polarised to the AS2832.1-1998 requirement and in accordance with AS2885.3. In conclusion the sacrificial cathodic protection system employed on the SEP is performing as per design expectations meeting the criteria specified in AS 2885.3. 4.3.3 Intelligent Pigging A pigging program was conducted during 2005 on the Glenco to Mt Gambier and the Katnook to Apcel laterals. The pigging process involved the running of five individual types of pigs starting with a gauging plate to ensure the larger pigging tools that are to follow will be able to successfully pass through the pipe work. Two types of cleaning pigs (brush and a magnet) were run multiple times to ensure the pipeline was clean, followed by an EGP which gathers electronic data relating to the geometry of the pipeline before a final pass with the CDP which is the tool that detects any corrosion in the wall be it internal or external. All data received from the pigging run was of good quality. A preliminary review of the pigging data did not show any defects with an ERF of 1 or greater. An assessment of whether any verification digs are to be undertaken is currently being considered and if required will be completed in 2006. 4.3.4 Electrical and Instrumentation

Accuracy Verification Testing was completed on a three monthly basis at all meter stations on the South East Pipeline System. Customer representatives attended AVT’s at several locations throughout the year. There were no significant issues associated with the AVT’s. Electrical compliance testing was carried out on all portable electrical equipment and residual current devices (RCD’s) at all sites. Installation of a differential pressure transmitter on the dust filter at APCEL took place during 2005. This was an action item from the incident investigation into the spontaneous combustion of filters during the pigging in 2004. Routine six monthly maintenance was carried out at all meter stations in May and November. This involved calibration of all non-billing transmitters, testing all remotely operated valves, calibration of all switches and testing of all associated systems. The communications system at the Nangwarry meter station was interrupted on two occasions during the year. The first outage was caused by a Telstra fault which had the communications down for a period of time. The second fault was caused by a lightening strike which damaged a modem. During all communications outages Epic Personnel and local contractors visited the site on a regular basis during each day of the outages to ensure that all systems were functioning normally. All other communications systems functioned without failure during 2005.

No major electrical failures were reported during 2005. 4.3.5 Mechanical All routine mechanical maintenance activities were completed as scheduled on the South East Pipeline system. This work involved MLV servicing, station dust filter inspection/replacement, door closure maintenance, coalescing filter inspection/maintenance and pig launcher/receiver maintenance. Routine inspection and maintenance was carried out on the pressure regulation/pressure relief systems at all South East Meter Stations on a 6 monthly basis. Maintenance tasks for the pressure control systems consisted of the inspection/overhaul of regulator seats, pilots and instrumentation filters to ensure correct operation of set points of the active/monitor and bypass regulation systems. Pressure Safety Valves were also checked to confirm correct set point, operation and alarming functions. Where applicable, overpressure isolation valve functions are tested to ensure satisfactory operation. All routine 6 monthly maintenance is documented via Epic Energy’s computerized asset management system (Maximo) and file copies are located within the central filing system. All buildings and structures are inspected and maintained as part of routine maintenance procedures are in sound condition. No major mechanical failures were reported for the South East Pipeline during 2005.

5 INCIDENT REPORTING There have been no reportable incidents during 2005 for the SEP system. 6 LAND MANAGEMENT 6.1 Land Owner Liaisons There are 72 separate landholders along the SEP route. All landowners on the SEP were contacted by phone during the year and a questionnaire was completed during each call. The questions were centered on people’s awareness of the pipeline location and their responsibilities with respect to works in the pipeline vicinity. All Landowners on the SEP were visited personally by an Epic representative during 2005. During the property owner visits the Epic representative completes a questionnaire designed to ascertain the landowner’s awareness of the pipeline system. In addition to the questionnaire a safety awareness information pack is provided which explains the requirements an individual must follow when working in the vicinity of an underground pipeline system. As part of Epic Energy’s awareness program all landowners were issued with a 2006 Epic Energy calendar reminding the landowner of pipeline safety. A new revised pipeline safety brochure was also developed and provided to the landowner. 6.2 Pipeline Safety Awareness Epic Energy implements a Community Awareness Program, which entails holding awareness meetings with communities along the pipeline route. The target is to hold meetings annually with


Page 10 of 19

CFS, MFS, Police, Ambulance, SES, Councils, civil works contractors, earth moving contractors, agricultural services companies quarry operators, rail authorities, irrigation and fencing installation contractors, forestry companies, developers and other interested parties along the SEP system.

The presentations focus on the general properties of natural gas, the process of gas transmission by pipeline, location of Epic Energy’s high pressure gas pipelines in the regions concerned, correct procedures when working within gas pipeline easements, pipeline threats and dealing with emergency situations. Attendees receive a pack of information including a ”Pipeline Safety and You" video.

Epic Energy conducted a number of these sessions during 2005 in the South East on the SEP system. 6.3 Pipeline Location and Referral Services During the course of 2005 19 enquiries were received via the Freecall 1100 “Dial Before You Dig” asset referral service, resulting in 3 in-field responses in relation to third party activities along the pipeline easement. There were no third party encroachments on the pipeline easement in 2005. 7 ENVIRONMENTAL MANAGEMENT During 2005 Epic Energy complied with all its environmental requirements as detailed in the Statement of Environmental Objectives. Appendix A contains the “Assessment of Declared Objectives” completed for the SEP system. 8 EMERGENCY RESPONSE Pipeline Licence 3&4 state that an ERE is to be conducted on the SEP system every two years. The last Emergency exercise on the SEP system occurred in 2004. (“Exercise Blue Lake”) While no specific ERE was carried out on PL3&4 during 2005 Epic Energy conducted 3 emergency response exercises on a number of other pipelines (MAPS, Beverley Lateral and SWQP) which tested the response capabilities of Epic Energy personnel. No major issues arose from these exercises. 9 REGULATORY COMPLIANCE Every endeavor is made to ensure that design, manufacture, construction, operation, maintenance and testing of all appropriate facilities, is carried out in accordance with AS2885. There are no known outstanding non compliances for the SEP system that Epic Energy is aware of against: • The Petroleum Act & Regulations 2000 • The Pipeline Licence (PL3&4) • The Statement of Environmental Objectives Any non-compliance identified is logged in the CMMS where it is tracked to conclusion. Significant items are reported through to PIRSA immediately. All other issues are raised at the quarterly meetings between Epic Energy and PIRSA.
